To investigate whether participants can activate only one spatially oriented number line at a time or multiple number lines simultaneously, they were asked to solve a unit magnitude comparison task (unit smaller/larger than 5) and a parity judgment task
magnitude (small left, large right). The effect has been named the SNARC effect, an acronym for spatial–numerical association of response codes. This has fed the idea that a mental number line is the core number representation system from which more complex forms of mathematical knowledge and ...

On average the verb ended 550 ms after onset; between 600 and 1900 ms participants heard a noun phrase or a prepositional phrase, which included a second lexico-semantic mismatch and ended the sentence. Compared with correct match conditions (blue line), lexico-semantic mismatches (red) elicited...
A predictive model for DSS was constructed using the following seven factors: age, grade, distant metastasis, number of positive lymph nodes, tumor extension, and tumor size (Fig. 1). The model had a C-index of 0.873 (95% CI 0.853–0.893) (Fig. 2). Figure 1 Nomogram for predicting th...
“I see the two studies as a natural progression, showing what happens to the only children who didn't have much interaction before Mindergaten, " Dr. Downey said. Another study he is working on shows that the same only children evaluated in kindergarten had caught up by fifth grade. ...
